FPD610

High Sensitivity Fast PIN Photodetector

K E Y S P E C I F I C AT I O N S■ Frequency Range DC-600 MHz■ Spectral Sensitivity from400-1000 nm or 950-1650 nm■ 3 dB Bandwidth DC-500 MHz■ Rise Time below 1 ns

A P P L I C AT I O N S■ Efficient Homodyne and Heterodyne

Extraction of Optical Beat Signals atFrequencies up to 600 MHz■ Detection of Low Light Level Signals■ Characterization of Pulsed or
Modulated Light Sources Features■ Detection of Chopped LightSources

The high sensitivity ultrafast PIN photodetector FPD610 product family combines
broad bandwidth and high gain at frequencies up to 600 MHz. These photodetectors are easy-to-use Si- or InGaAs-PIN photodiode packages with an integrated
high-gain, low-noise transimpedance amplifier.
The 3 dB bandwidth of the DC-coupled device is 500 MHz.
Models for both visible and near infrared range are available, both with either freespace or fiber coupled optical input. The compact design of these detectors allowsfor easy OEM integration. Included with each amplified photodetector is a low
noise power supply, which features a universal AC input.
